The r intc interrupt controller seems to do a lot of things :
- It can handle the NMI interrupt
- It have local interrupts for some device that also can be muxed with GIC
- It can serve as an forwarder for the GIC
It's mostly used for deepsleep/wakeup if I understood correctly and we do not
support this on arm64.
For now just forward everything to the GIC so interrupts works again for device
which now have this interrupts controller set since dts v5.12

(cherry picked from commit 15565e0a21)
The vmbus ISR needs to live in a trampoline. Dynamically allocating a
trampoline at driver initialization time poses some difficulties due to
the fact that the KENTER macro assumes that the offset relative to
tramp_idleptd is fixed at static link time. Another problem is that
native_lapic_ipi_alloc() uses setidt(), which assumes a fixed trampoline
offset.
Rather than fight this, move the Hyper-V ISR to i386/exception.s. Add a
new HYPERV kernel option to make this optional, and configure it by
default on i386. This is sufficient to make use of vmbus(4) after the
4/4 split. Note that vmbus cannot be loaded dynamically and both the
HYPERV option and device must be configured together. I think this is
not too onerous a requirement, since vmbus(4) was previously
non-functional.

This flag was originally added in back in r94332 but the flag is a no-op

This is a prerequisite to using these functions outside of ddb, but also
provides some cleanup and minor refactoring. This code is almost
entirely duplicated between the two implementations, the only
significant difference being the lack of dbreg synchronization on i386.
Cleanups are:
- demote some internal functions to static
- use the constant NDBREGS instead of a '4' literal
- remove K&R definitions

Tested with glibc test suite.
The C variant in libkern performs excessive branching to find the zero
byte instead of using the bsfq instruction. The same code patched to use
it is still slower than the routine implemented here as the compiler
keeps neglecting to perform certain optimizations (like using leaq).
On top of that the routine can be used as a starting point for copyinstr
which operates on words intead of bytes.
The previous attempt had an instance of swapped operands to andq when
dealing with fully aligned case, which had a side effect of breaking the
code for certain corner cases. Noted by jrtc27.

This node is part of an A10-NSP (L2-BSA) development.
Carrier networks tend to stack three or more tags for internal
purposes and therefore hiding the service tags deep inside of the
stack. When decomposing such an access network frame, the processing
order is typically reversed: First distinguish by service, than by
other means.
This new netgragh node allows to bring the relevant VLAN in front (to

It appears that production versions of EPYC firmware get the _STA method right
for these nodes. In fact, this workaround breaks on production hardware by
including too many uart nodes. This work around was for pre-release hardware
that wound up not having a large deployment. Move this work around to a kernel
option since the machines that needed it have been powered off and are difficult
to resurrect. Should there be a more significant deployment than is understood,
we can restrict it based on smbios strings.

This code implements a version of the devres framework found
working for various iwlwifi use cases and also providing functions
for ttm_page_alloc_dma.c from DRM.
Part of the framework replicates the consumed KPI, while others
are internal helper functions.
In addition the simple devm_k*malloc() consumers were implemented
and kvasprintf() was enhanced to also work for the devm_kasprintf()
case.
Addmittingly lkpi_devm_kmalloc_release() could be avoided but for
the overall understanding of the code and possible memory tracing
it may still be helpful.
Further devsres consumer are implemented for iwlwifi but will follow
later as the main reason for this change is to sort out overlap with
DRM.

Use the existing legacy PCI driver as the basis for shared code
between the legacy and modern PCI drivers. The existing virtio_pci
kernel module will contain both the legacy and modern drivers.
Changes to the virtqueue and each device driver (network, block, etc)
for V1 support come in later commits.
Update the MMIO driver to reflect the VirtIO bus method changes, but
the modern compliance can be improved on later.
Note that the modern PCI driver requires bus_map_resource() to be
implemented, which is not the case on all archs.
The hw.virtio.pci.transitional tunable default value is zero so
transitional devices will continue to be driven via the legacy
driver.
